摘　　要：为探求宁夏水环境承载力的变化趋势,根据宁夏2013—2015年统计资料,通过灰色关联度分析、计算18个待选指标与水环境承载力的关联度,并从中选出10个关联度较大的指标构建宁夏水环境承载力的评价指标体系;在此基础上进行主成分分析,并结合指标数据变化进行水环境承载力动态变化分析.结果表明,工业废水排放量、城市污水处理率、工业污水处理回用量、人均GDP、人均用水量、万元GDP用水量和万元工业增加值用水量是影响宁夏水环境承载力的主要因素.2010—2015年宁夏水环境承载力呈逐年上升趋势.In order to explore water environmental carrying capacity variation trend in Ningxia, this article calculated the correlation degree between 18 indexes to be selected and water environmental carrying capacity, and chose 10 high correlated indexes to build evaluation index system of water environment carrying capacity in Ningxia according to the statistical information from 2013 to 2015 in Ningxia;It carried out principal component analysis basing on this, and dynamically analyzed water environmental carrying capacity combining with indicator data change. The result shows that, the key factors affecting the carrying capacity of water environment in Ningxia are: the industrial wasterwater discharge, the urban sewage treatment rate, the reuse of industrial sewage treatment, the GDP per capita, the per capita water consumption, the water consumption of 10,000 Yuan GDP, and ten thousand Yuan industrial added value water consumption. The bearing capacity of water environment in Ningxia is increasing year by year from 2010 to 2015.
